I am trying to adapt the engine to a 480x320 resolution (your guess is right: iPhone resolution) but I am "still" not an expert, so I would like to have some advice on what should I take in consideration while doing this.

I am starting with the tile editor, being more or less successful with adapting the resolution but the tiles are not being transported properly in the destination position.

More questions are: how can I use source png tiles bigger than 256 tiles?

Also, a event file handling more than 256 events would be great. My plans are to have big action there
